Risamann, Lorain, Ohio, assignmto Richard Paul Rissmann, Lorain, Ohio This invention relates to window screens, and has special reference to rolling screens, the object being to provide a screen which may be readily attached to the outer side of a window sash without marring the woodwork or necessitating substantial structural changes therein. It is also an object of the invention to provide a rolling window screen which will not detract from the appearance of the window to which it is applied and which will effectually shed water to prevent its access to the interior of the screen housing to the detriment of the same. It is also an object of the invention to provide means whereby the screen may be readily detached from the window sash when it is desired to clean the window.- These stated objects, and other objects which will appear as the description proceeds, are attained in such a structure as is illustrated in the accompanying drawings and the invention resides in certain novel features which will be particularly defined in the appended claims.

In the drawings:

Figure 1 is a vertical section through a window having my improved rolling screens applied thereto.

Figure 2 is a horizontal section on the line 2-2 of Figure 1.

Figure 3 is an enlarged detail vertical section of the lower rail of the lower sash showing the connection of the screen therewith.

Figure 4 is a similar view of the upper portion or lintel of the \m'ndow frame with the adjacent parts of the upper sash and the screen connections.

Figures 5 and 6 are detail perspective views of tracks or guides in which the screens slide.

Referring to the drawings, in detail, the numeral I indicates a window frame, 2 designates the lower sash, and 3 designates the upper sash. In carrying out the present invention, a metal housing 4 of copper or other non-corrosive metal is secured upon the sill 5 of the window frame, the upper and outer sides of the housing being united through a curved portion so that any water or other moisture which might otherwise tend to collect thereon will be shed onto the sill and thereby drained oil to the ground. The housing is provided with a slot 6 in. its topas shown in Figure 3 and'mounted within the housing is a spring roller 1 to which one end of a window screen 8 is firmly secured. The opposite end of the screen is secured to a metal rail or clamping strip 9 which clasps the end edge of the screen and is secured thereto by rivets or similar fastenings. The reinforcing strip or rail is formed into an overhanging hook in along its upper edge and on its inner side is provided with a lug H in which is rotatably mounted the upper end of a fastener l2, the

lower end of said fastener being formed into a crank l3 adapted to fit within a. recess l4 formed in the lower edge and outer side of the bottom rail of the lower sash. The fastener, as will be understood, is a light rod having its upper end rotatablyfltted in the lug ll so that the crank at its lower end may be turned to fit within the recess M or lie against the housing and permit the sash to ride past the same. The housing 4 is provided with upper and lower flanges l5 and I6 along one side of the slot 6 and a strip I! of rubber or similar material is secured between and held by said flanges to bear upon the screen and prevent the entrance of insects or the access of water to the interior of the housing when the window is raised. Secured upon the bottom rail of the sash near the upper edge thereof is a metallic strip l8 which is preferably resilient so that it will tend to fold or lie against the rail and is given an ogee formation so that its lower edge will be spaced from the rail and is formed into a hook H! which will extend under and engage the hook HI whereby as the sash is raised thescreen will be drawn upwardly from the housing. When the sash is lowered the spring roller I will cause the sash to wind, as shown in Figure I and as will be readily understood. A sheath or deflecting plate 20 is provided over the outer surface of the strip l8 and is secured by the same fastening 2| that secures the latter to the rail,

an additional fastening, such as a rivet 22, being inserted through the two strips below their upper edges, as clearly shown in Figure 3. The lower free edge of the sheath or outer strip, when the sash is fully lowered, extends outwardly over and beyond the flanges l5 and I6 whereby any water falling upon the sheath will be deflected from the flanges and will drain oil over the housing.

In order'that there may be no gap or open space between the upper and lower sashes when the upper sash is raised, only partly, a recessed strip 23 is secured upon the under side of the meeting rail 24 of the upper sash and holds a strip of rubber or similar material 25 which projects beyond the meeting rail and bears against the glass in the lower sash, as clearly shown in Figure 1. 1 v

Secured to the parting bead 26 of the window frame is a tracker guide 21 which receives the side edge of the screen and holds the same to a straight line, as it is unwound. This track or guide is formed integrally from a single strip of metal and includes parallel jaws 28 and 29 with a side flange 30 at the base of the inner jaw through which fastening devices may be inserted into the parting bead to secure the track in position. The edge of the jaw 29 remote from the base flange is turned laterally and then inwardly toward theparting bead, as shown at ll, whereby a tongue will be produced to bear against the screen and hold it with a sliding flt against the outer jaw II, as will be understood upon reference to Figure 6.

A metal housing s2 is secured to the lintel or upper cross member of the window frame and a spring roller 33 is mounted in said housing, the housing having a slot 34 in its lower side adjacent the window irame, and a screen II being wound upon the roller and having one edge iirmly secured thereto. The free edge of the 'screenisfirmlysecuredinametalrail,

similar in construction to the rail 9 applied to the lower screen, and said rail It has an upturned hook 31 on its outer side, as clearly shown in Figure 4 of the drawings. Secured to the upper rail of the upper sash is a housing or bracket 38 having its outer wall formed into an inwardly extending overhanging hook I. which engages over the hook II, as clearly shown in Figure 4, whereby as the upper sash is lowered the screen will be drawn down and when the upper sash is raised the screen will be rewound upon the spring roller 33. Pivotally mounted upon the upper side of the bracket 38 is a fastening lever or latch 40 having its inner end upturned, as shown at 4|, to constitute a handle and having its outer end adapted to extend under the hook 31, as shown in Figure 4, a stop finger I! being formed upon the upper side of the latch to bear against the rail 36 and thereby prevent accidental release of the screen from the hook 39. when it is desired to release the screen, as, for instance, when the window is to be washed, the window is lowered sumciently to permit the operator to reach over the upper rail and turn the latch 40 so that it will be disengaged from the rail 3| and hook I'I whereupon the rail may be easily grasped by the operator and disengaged from the hook a so that it may be drawn back into the housing 32. The screen, however, will not pass fully into the housing, inasmuch as the bill of the hook 31 will impinge against the bottom of the housing at the outer side of the slot 34 and thereby arrest the retracting movement of the screen. A track 43, corresponding in all essential respects to the track 28, is secured along the outer bead of the window frame and the edge of the screen 35 is engaged and travels through said track. This track does not have the attaching flange 30 which is present in the lower track, but is secured in position by fastenings inserted through openings 44 provided therefor in its two side walls.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have provided an exceedingly simple construction whereby rolling window screens may be attached to the outer sides of double sash windows without detracting from the appearance of the window or marring the woodwork and by which moisture will be deflected from the rails of the window sashes so that such moisture cannot affect the operation of the screens. The screens may be very easily detached from the respective sashes when such removal is desired for any purpose. To detach the screen from the lower sash, the sash is raised sufiiciently to give the operator access to the latch i2 whereupon the latch is given a quarter turn to disengage it from the recess II and the edge of the screen is then lifted suiilciently to disengage it from the supporting hook I, thespring roller 1 then electing rewinding of the screen in the well-known manner. The strip I! not only prevents the entrance of insects and foreign matter to the housing 4, but also serves asastoptobeengagedbythehook II and thereby prevent the screen being withdrawn fully into the housing. To release the screen from the upper sash, the sash is partly lowered until access can be had to the latch Ill whereupon said latch is released, as previously stated.

The tracks or guides are wide enough to accommodate a moderate range of .widths in windows, and the housings I and 32 may be telescopic to provide for such variance.

- Having thus described the invention, what is claimed as new is:

1. In a window screen including screening wound upon a roller, a rail secured along the outer end of the screening and formed with a hook, and a bracket adapted to be secured to a window sash and project therefrom, said bracket being provided with a hook for engagement by the hook of the rail, a latch pivoted to said bracket for movement into and out of position to engage the hook of the rail and prevent accidental separation of the hooks.

2. In a window screen including screening wound upon a roller, a rail secured along the outer end of said screening and having a portion bent back upon itself to provide a hooked portion, and a member adapted to be secured to a sash with a portion extending toward the rail and bent back upon itself to form a hooked portion disposed in opposed relation to the hooked portion of the rail 'and interengaged therewith to cause the screening to be drawn to an extended position when the sash is moved to an opened position, a latch movable into and out of position to retain the hooked portion of the rail in interfitting engagement with the hooked portion of the member carried by the sash and prevent accidental separation thereof.

3. In a window screen structure including a strip of screening, a rail secured along an end edge of the screening and provided with an outwardly extending overhanging hook and with a lug for projecting from a side of the rail for extending towards a window sash and adapted to limit movement of the screening into a housing, and a hook to be secured to the window sash and engage under the overhanging hook of .the rail whereby the screen will be caused to follow the movement of the sash, means for disengaging the said hooks carried by said lug and movable into engagement with the sash to prevent accidental movement of the hooks out of engagement with each other.

4. In a window screen structure including a strip of screening, a rail secured along an end edge of the screening and provided with an outwardly extending overhanging hook, an extension projecting from said rail in position to engage a housing and limit movement of the screening into the housing, and a hook to be secured to a window sash and engage under the overhanging hook of the rail whereby the screening will be caused to follow the movement of the sash, a fastener having its upper end rotatably connected with the extension and its lower end formed with a crank portion movable by rotation of the fastener into and out of position to engage under a portion of a window sash and prevent accidental paration of the hooks.
